Rocket propellant is mass that is stored in some form of propellant tank, prior to being used as the propulsive mass that is ejected from a rocket engine in the form of a fluid jet to produce thrust. A fuel propellant is often burned with an oxidizer propellant to produce large volumes of very hot gas. These gases expand and push on a nozzle, which accelerates them until they rush out of the back of the rocket at extremely high speed, creating thrust. Sometimes the propellant is not burned, but can be externally heated for more performance. For smaller attitude control thrusters, a compressed gas escapes the spacecraft through a propelling nozzle.
Chemical rocket propellants are most commonly used, which undergo exothermic chemical reactions to produce hot gas used by a rocket for propulsive purposes.
In ion propulsion, the propellant is made of electrically charged atoms (ions), which are electromagnetically pushed out of the back of the spacecraft. Magnetically accelerated ion drives are not usually considered to be rockets however, but a similar class of thrusters use electrical heating and magnetic nozzles.
Rocked down you wanna feel but you coutind be oh yeah (2x)
But if you want to get around
Get around from the break of dawn
To the test of what it seems
But if you want to get allright
I tell your trick that im breaking for
Another round of what it feels yeah
But if you want to get me down
Turn your back from the break of dawn
Another gest of what it meens yeah
But if you want to get allright
I tell your trick that im breaking for
Another gest of what it meens yeah
Lets go
Rocked down you wanna feel but you coutind be oh yeah (2x)
But if you want to get around
Get around from the break of dawn
Another gest of what it needs yeah
But if you want to get allright
I tell your trick that im breaking for
Another gest of what he seels yeah
But if you want to get me down
Turn your back from the break of dawn
Another gest of what you need yeah
But if you want to get allright
I tell your trick for the break of down
Another gest of what you need yeah
So now you wanna feel the day
Turn your back of what you need
Seeing colours in the rain
Not me
So if you wanna show this grey
Turn your back of what you need
Flying high across the sea
